SASH-CORD GUIDE.

SPECIFICATION forming part of Letters Patent No. 607,739, dated July 19,1898.

Application filed February 23, 1898. Serial No. 671,324. (No model.)

To all whom, it. may concern:

Be it known that 1, WILLIAM R. FOX, a citizen of the United States,residing at Grand Rapids, county of Kent, and State of Michigan, haveinvented certain new and useful Improvements in Sash-Cord Guides, ofwhich the following is a specification.

My invention relates to improvements in sash-cord pulleys and shellscomposed of sheet metal; and the object of the invention is to provide aconstruction which may be produced at an extremely low cost by stampingfrom sheet metal and in which all necessity for riveting the partstogether may be dispensed with.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevationof one form of the invention. Fig. 2 is aplan View. Fig. 3 is abottom View of the same. Fig. 4 is a detailedsectional View showing the pulleyaxle serving as the connecting-rivetbetween the two sides. Fig. 5 isa face view of amodified form, and Fig.6 a side view of. the same, while Fig. 7 is a similar view of a stillfurther modification. Fig. Sis a detail sectional view of the overlappedends D.

The pulley A may be of any construction, having a hub fitted to turn onthe stationary bolt or axle C. V

In sash-pulleys it is an important object to eifect even a very smallsaving, either of 1abor or material, in one article, since they are usedin such large quantities and the competition is very close. Ithereforehave made the shell orcase in two pieces 13, each of which forms thewall of the pulley-case on one side and on its upper edge is bent overat right angles to its side plane, so as to extend over the face of thewood in which it is inserted and thus form the face of the case insteadof the ordinary face formed by bending the sides out of a single pieceof sheet metal. The two sides may be exactly alike and all be struck upin one die at one operation, so that there is asaving of metal and work.The ends are curved inward to form a half-round end of the case, asshown in Fig. 2. Also the edges of the ends are turned out to form fiatbearing-flanges in planes parallel to the general plane of the case, andthese flanges B, when the parts of the case are in place, bear firmly oneach other. The edges may be serrated to facilitate the entrance of thecase into the wood, as shown in Fig. 1. In the case thus made of twoparts Ihave found it practicable to use no other connection for the twosides than the contact-bolt on which the wheel turns. As ordinarily madethis bolt or axle serves .to hold the parts together, but does notdetermine or maintain their relative position. By combining, however,the two side pieces so made as above described with a bearing-bolthaving shoulders and reduced polygonal ends fitted to correspondingholes in the sides, these holes being alike in shape and arrangement,the two parts are held also against turning out of relation to eachother.

The bolt is shown at O, and its outer reduced ends are, as shown in Fig.1, square and fit square holes, the inner part being round to affordbearing for the wheel. The reduced ends fit the holes and when upsethold the parts in their proper relation, since neither can turn on thebolt independently of the other, and the case may be handled and shippedwithout disarrangement. I

A circular depression I) is stamped in the centerof the wall and astiifening-corrugation 61 in the lower edge. For further scour ity and asomewhat more elaborate case the sides may also be formed with flangesD, the sheet metal being out to form these flanges, which are turnedinto a plane at right angles to the sides of the case, and when thesides are put together these flanges overlap each other, as shown at Din Figs. 5 and 6. Holes d are made in the overlapping portions inposition to register and to receive nails or screws for securing theparts firmly to the wood, thus forming a face-plate for the case andadditional security. The metal may be countersunk about the hole toreceive the head of the nail or screw, the countersunk por tions forminga locking connection. Flanges maybe made as shown in Fig. 5 or morefull, as shown in Fig. 7 at D It will beobserved that in all forms thetwo sides are alike'and when put together are held by the bolt at thecenter in their proper position against dis placement, and in thiscondition may be haning inwardly-turned abutting ends in combinationwith the pulley-axle having non-cin cular ends engagingcorrespondingly-shaped holes in the sections, said pulley-axle holdingthe abutting ends together, and the sections against all relativelyindependent movement, substantially as described.

2. A sash-cord guide having a body portion formed of duplicatesheet-metal sections having inwardly-turned abutting ends and bentoverupper edges in combination with the pulley-axle having non-circular endsengaging correspondingly-shaped holes in the sections, said pulley-axleholding the abutting ends together, and the sections against allrelatively independent movement, substantially as described.

3. In a sash-cord guide, a body portion formed of two sheet-metalsections having in wardly-turned abutting side edges, and havingoutwardly-turned upper edges forming bearing-flanges, said flanges beingextended at the ends and overlapping each other and having alining holesin said overlapped portions, substantially as described.

4. In a sash-cord guide, a body portion formed of two sheet-metalsections having inwardly-turned abutting side edges, and havingoutwardly-turned upper edges forming bearing-flanges, said flanges beingextended at the ends and overlapping each other and having alining holesin said overlapped portions, the edges of said alining holes beingswaged downwardly to form countersinks, substantially as described.

5. In a sash-cord guide, a body portion formed of duplicate sheet-metalsections havin g inwardly-turned ends provided with abutting flangesan'd outwardly turned upper edges in combination with a pulley-axlehaving reduced and non-circular ends holding the abutting flanges incontact, substantially as described.

In testimony whereof I affiX my signature in presence of two Witnesses.
